WINDOW-ram.

Specification of Letters l'atent.

Application filed January 9, 1818. Serial 110.3119.

To all wkomitmay concern:

Be it known that I, Ismnn KLAYMAN, a citizen of Russia, residing at Baltimore, in the State of ,Ma land, have invented certain new and use Improvements in Window-Frames, of which the following is a specification.

The present invention relates to window frames and has for its purpose to provide a frame having movable portions which will readily allow of removing the window sashes and replacing. the same, in a simpleand easily performed manner.

The invention is shown by way of illustration in the accompanying drawing wherein:

Figure 1 is a front elevational view thereof.

Fig. 2, a transverse sectional view on the line 22 of Fig. 1, and

Fig. 3, an enlarged sectional view showing the device for securing the front strip to the window frame.

Referring to the construction in further detail, the frame consists of a side portion 1, an outer and inner portion 2 and 3. A parting strip 4 is detachably secured in a oove of theportion 1, by s ring tensioned firs 5 (one being shown). ach bar 5 fits in a metal casing 6 and the tensionin spring 7 surrounds the bar 5 within sai casing. y

A hand engaging member 8 is carried by each bar 5 to withdraw said bar from engagement with a hook 9 carried b the removable strip 4. Said strip 4 t us provides the division piece WhlCh forms the two slideways for the window sashes.

A stop strip 10 is secured to the art 1 adjacent the portion 3 by means 0 bolts 11 (one being shown) each having a hooked end 12-aflapted to engage in the aperture of a plate 13 secured to the part 1 as shown. The bolt 11 has an inner projecting portion 14 whereby said bolt may be readily depressed to disengage the locking elements 12 and 13. The bolt 14 is normally held under tension and in locked position by the spring 15, as shown.

The slot or opening in the plate 13 is sufiiciently large to allow of the hooked end of the bolt 11 being moved laterally when the stop strip 10 is to be removed. By this arrangement the hooked end 12 of the bolt 11 will easily clear said apertured plate 13.

It is obvious that those skilled in the art may vary the details of construction and arrangement of parts without degarting from the spirit of my invention, an therefore I do not wish to be limited to such features except as may be required by the claim.

Having thus described my said invention, what I claim as new and desire to secure by Letters Patent is:

The combination with a window frame, of a stop strip disposed along one edge thereof, said window frame having an apertured plate covered by said stop strip, and a' spring tensioned latch mounted on the stop strip havin a hooked end engaging the apertured p ate and holding said stop strip in position thereon, substantially as set forth.

In testimony whereof I afiix my signature in the presence of two witnemes.
